PHONOGRAPHIG ATTACHMENT. 7

Application filed May 5, 1919. Serial No. 294,859;

Be it known that I, EWILLIAM C. Ron, a

citizen of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Phonographlc Attachments, of which improvement thefollowingis a specification.

My invention relates to improvement in phonographic'attachments forstarting and sto ping the mechanism used to rotate the table carryingthe record. The object of this invention is to produce a mechanism ofthis kind having the following characteristics, viz

1. The capacity of starting the mechanism by the movementof' the tonearm.

2. Of automatically stopping the machine at the end or completion of anyrecord, regardless of its length and without special or previousadjustment or arrangement, and

Finally, the production of a stop and start mechanism for phonographshaving a minimum ofparts with a maximum of strength therein, and whichcan be made at small cost.

I accomplish these objects by means of the device hereinafter morespecifically de-' scribed, reference being had to the accompanyingdrawings forming part hereof, in which I Figure 1 is a plan view of thetop of the machine,

eferring to the said drawings, and par ticularly to Figures 1-7inclusive; 1 isthe box or receptacle within which the actuatingmechanism of the usual construction is secured. 2 is the table orplatform which is centrally mounted upon. the spindle 3i which isadapted to be connected with the actuating mechanism (not shown) in theusual manner. The said table is adapted to carry the record 4. 5 is thetone arm of the usual construction and is supported on one side of thebox in the usual manner. 6' is a worm gear on one end of the shaft .7which meshes. with the toothed pinion 8 on the s indle 3. The oppositeend of said shaft 2 is also provided with a Worm gear 9 which mesheswith the pinion 10, which is integral with or secured to the thimble 11}which is mounted on the spindle 12. 13 is a toothed pinion-looselymounted on the upper end of the thimble 11, said toothed pinion beingfree to move in one direction onl when engaged by the serrated or tootheedge of the arm 14, which is connected to and carried by the tone arm 5.15 is a friction washer mounted on said thimble 11 between the shoulderthereon and the lower side of the loose pinion 13, the function of saidwasher being to produce sufiicient friction to hold the pinion againstmovement momentarily, whereby the continued rotation of the thimblecauses the ball 16 to be wedged against the thimble, locking the pinion'13 to the thimble and causingt thesshiftable member 17 to move orswerve toward the right to the extent of the play between the teeth ofthe toothed arm"14, the teeth of the pinion, thus throwing the hookedend of the arm 18, which is integral with the shiftable member 17 out ofengagement in the notch b in the edge of member 19. Under suchconditions the retraction of the spring 20 one end of which is connectedgagement with the'inner surface of the periphery of the table 2, asshown in dotted hooked end of arm 18 in contact with the edge of bothmembers 19 and 23. .It will be seen that the member 17 is pivoted on theshaft 3, and that the arm 18 is intregal' to the lines Figure 1 stoppingthe same. The said members 19 and 21, with the member 23 and theauxiliary parts thereof, constitutes the stop'and start mechanism. Thesaid member 21 comprises a substantially circular plate-mounted on thepin 24, on which is also mounted the member 19, the said member 23having a handle or projecting arm 25, which constitutes the usual stopmeans, as by throwing the said handle, as shown in dotted lines. Figure1 carries the highest curved portion e,-of said member 23 intoengagement with the hooked end of arm 18, throwing the samel out of engagement with the notch b, and permitting the retraction of the spring20, as heretofore described, to carry the brake arm 22, into contactwith the inner surface of the rim of the table, stopping the same. Thecompression spring 26 one end of which is secured to the upwardlyprojecting prong g, on the member 23 and the opposite end rong d onmember 21, serves to throwt e handle 25 into, and out of operativeposition.- Each of said members 19 and 23 are provided with,respectively, re cesses h, k in which the prong d on member 21 projects,the length of said recesses limiting the rotary movement of both saidmembers. The spring 27 serves to hold the with the member 17,. though itmay be secured thereto in any suitable manner. It

will thus be seen that the rotation of the member 17 will cause acorresponding "rotation of the arm 18, the outward extremity of whicharm engages the member 19 in the slot 6. I

With this arrangement of my invention, it' will be seen that when thephonograph needle is carried into operative engagement with the groovesof the record, the teeth of thev arm 14 will pass into engagement withthe teeth on the pinion 13. The pinion 13 is arranged to rotate relativev to the pinion 10, to permit such engagement between the said teeth onthe arm 14 and- The result is that the pinion 13 is locked intoengagement with the shaft 12 through the action of the ball.

The whole member 17 is then rotated on the shaft 3, and the-outerextremity of the arm 18 is lifted out of the slot 6 in the to theposition indicated by the dotted linesof Fig. 1, wherein the arm14-engages the trigger projecting inits path which is shown in ig.-1 andFig. 9, extending upwardly from the rotatable member 19; the motion ofthe member 14 further to the right will rotate the member 19- about thepoint 24 until the hooked endv of the lever 18 will fall into the notchB on the member 19, the arm 18 being drawn into the said notch by thespring 27.

The rotation of the member 19 will cause the brake arm 22 to moveclock-wise about the center 24, and to become disengaged from theperipheral flange of the table 2, where, consequent to the action of theautomatic' stop mechanism hereinbefore de scribed, said brake armmaintained the brake contact carried at its end in frictional engagementwith the platform or-turn-table 2- to prevent its rotation. Theturn-table will now rotate clock-wise, and the operator will place theneedle of the phonograph reproducer in the record groove at the startthereof, whenceforth, the tone arm 5 will be rotated clockwise to theend of the rec-' 0rd, when it-will again come to rest and Wheneverautomatic starting of the turntable rotation is not desired, theturn-table may be started or stopped by manipulating the handle 25in theone or the other direction to place the brake 22 into or out ofengagement with the turn-table flange.

in Figures 14 and 15 I show a modified form of my invention and which ispreferred, on account of its greater simplicity, to that illustrated inFigures 1 to 13 inelusive. In said Figures 14 and 15, .28 is a spindlewhich is adapted to be connected with the drivingmechanism (not shown)in the usual manner. The said spindle is provided with a worm 29, whichmeshes with Ill] a gear wheel 30 on one end'of the shaft 31,

the opposite end of said shaft having a worm 32 which meshes with andtransmits power to the gear wheel 33 which is mounted on the lowerend ofthe spindle 34, the ,lower end of which is supported in a bearing formedin the shiftable link 35. .The opposite end of said link is pivotallyconnected to and mounted on, one end of the link 36, the opposite end ofsaid link being mounted on the pin 37 and terminates in a handle 38. Athimble 3-9 is mounted on said spindle 34 and supports a gear wheel 40loosely mounted on the upper end of said spindle 34. The said gear Wheel40 meshes with the teeth or serrations on the end of the arm 41 which isconnected to the tone arm of the machine in a similar manner to arm 14.42 is an arm one endof which is mounted on the thimble 43 which ismounted on the pin connecting links 35 and 36. The opposite end of saidarm terminates in a hooked portion adapted to engage in a notch n on themember 44, which member is mounted on the pin 45 and is provided with ahandle 46 and a hooked prong 47 adapted to engage over the arm 42. Theprojecting finger 48 and the brake arm 49 are also provided. 1

In Figures 16 and 17 I show another modification of my invention. Insaid figure 50 is the box or receptacle; 51 and 52 are respectively, thetable and record thereon; 53 is the spindle adapted to be connected tothe operative mechanism 'in the usual manner. The said spindle hasmounted thereon a gear wheel 54 which meshes with and transmits motionto the gear wheel 55 on one end of the shaft 56, the opposite end ofsaid shaft having mounted thereon the worm 57 which meshes with the gearwheel 58 mounted on a pin 59 secured in the plate 60. 61 is a similargear mounted upon the pin 59 above the gear wheel 58. The said gear 61meshes with the gear wheel 62 on the spindle 63 which is mounted on oneend of the shiftable link 64. The opposite end of said link is connectedto the vertically disposed pin 65 to the upper end of which one end ofthe arm 66 is secured. The upper end of said spindle 63 has mountedthereon the loose gear 67 which meshes with'the .teeth or serrations onthe end of the arm 68, which is attached to the tone arm 69 in a mannersimilar to arm 14. The said arm 66 projects towards the outer peripheryof the table and is provided with a recess an, adapted to engage thebrake arm 69 of the stop and start mechanism. The

said stop and start mechanism comprises a plate 70 carrying said brakearm andhaving an upwardly projecting prong 71to which one endof a sprlng72 issecured, the opposite end of which spring 72 is connected to a pinin the frame of the machine. The saidplate is provided with the usualstart lever 73 and the stop lever 74.
